WAGO 281-101 2-Conductor Through Terminal Block 4mm² 32A Gray

The WAGO 281-101 is a 2-conductor through terminal block from the 281 Series, designed for simple and secure electrical connections in industrial and building applications. Using CAGE CLAMP® spring-pressure technology, it accepts solid and fine-stranded copper conductors from 0.08 to 4 mm² (28 to 12 AWG) with no need to crimp ferrules or otherwise prepare the conductor. Rated 32 A and 800 V per IEC/EN 60947-7-1 (OVC III, pollution degree 3), the block mounts horizontally on DIN-rail 35 x 15 or 35 x 7.5.

Features and benefits:

• CAGE CLAMP® spring-pressure connection is maintenance-free and accepts all conductor types - solid, fine-stranded, and aluminum - without ferrule preparation.
• Aluminum conductor termination is supported up to 4 mm² when WAGO Aluminum Contact Paste 249-130 is used; the paste prevents oxide film, fresh oxidation, and electrolytic corrosion at the clamping point.
• Lateral marker slots enable side marking for clear circuit identification across the rail assembly.
• Wide continuous operating range (-60 ... +105 °C) and UL94 V0-rated PA66 housing handle demanding thermal environments.
• Broad approval portfolio - UL, CSA, KEMA/KEUR, CCA, plus four marine certifications (ABS, BV, DNV GL, PRS) - supports global and shipboard installations.

Applications:

• Through-wiring in industrial control panels and switchgear enclosures.
• Electric motor wiring assemblies on DIN-rail 35 x 15 or 35 x 7.5 (280/281 Series motor wiring family).
• Distribution boards in commercial and residential building installations.
• Marine and offshore electrical panels where ABS, BV, DNV GL, or PRS certification is required.
